Paper Title
High-Throughput FPGA Implementation of AES-512 Encryption Algorithm

Abstract
This paper describes the growing need for stronger encryption methods in response to the surge in cyber threats and data breaches. The Advanced Encryption Standard (AES), a widely used algorithm for secure data exchange, is conventionally limitedtokeysizesofupto256bits.Themainobjectiveof this paper is to investigate the design and implementation of an extended 512-bit AES (AES-512) to achieve enhanced security for critical and high sensitivity applications. The proposed AES- 512 architecture is developed on a Xilinx Virtex Ultra Scale+ FPGA, and its performance is evaluated in terms of resource utilization, latency, power consumption, and throughput. Comparative analysis with AES-128 and AES-256 implementations reveals that, despite increased computational complexity, AES 512 can be efficiently executed on high-performance FPGA platforms, making it a promising candidate for next-generation cryptographic systems.
